Maintenance and adjustment procedures

The section describes the servicing procedures for each item of the Periodic

Maintenance requirements.

Storage battery

Inspect at initially 1000KM（600 miles，2

months），and every 6000KM（4000 miles，

12 months）thereafter

□ Uncover seat, and then remove the battery box cap in the

Middle of helmet barrel.

□ Disconnect negative pole line end, positive end, and then remove battery；

□ Measure the voltage between the two ends of

battery with

voltage gauge，charge if the voltage is below

11,9V

10

Cylinder head nuts and exhaust pipe bolts

Tighten at 500 km, and each service.

If cylinder head nuts are not tightened to the

specified torque, may result in leakage of

compressed fuel-air mixture and reduce

output, tighten the cylinder head nuts in the

following procedures:：

1． Remove the frame lower covers.

2． Remove the cylinder head cover bolt.

3． Remove spark plug cap.

4． Tighten the nuts evenly one by one to the their

specified torque. Tighten the nuts in the order

indicated.

Tightening torque：

Cylinder head nut：15-18N.m

Exhaust pipe bolt：15-18N.m

Cylinder and cylinder head

Remove carbon every 6000 km（4000 miles，12

months）

Carbon deposits in the combustion chamber

and the cylinder head will raise the compression

ratio and may cause preignition and

overheating. Carbon deposited at the exhaust

port of the cylinder will prevent the flow of

exhaust gases, reducing the output. Remove

carbon deposits periodically.

11

SPARK PLUG

Neglecting the spark plug maintenance eventually leads to difficult starting and poor

performance. If the spark plug is used for a long time, the electrode gradually burns

away and carbon builds up along the inside part. In accordance with the periodic

table, the plug should be removed for inspection, cleaning and to reset the gap.

z Carbon deposits on the spark plug will prevent

good sparking and cause misfiring. Clean the

deposits periodically.

z If the center electrode is fairly worn down, the

plug should be replaced and the plug gap set to

the specified gap using a thickness gauge.

Thickness gauge

Spark plug gap：0.6-0.7 mm (0.024-0.028 inch)

Check the spark plug for burnt condition. If

abnormal replace the spark plug as indicated in the

chart.

NGK TROCH REMARKS

BPR7HS E8RTC If the standard plug is apt to get wet, replace with the plug.

BPR8HS E7RTC Standard

BPR9HS E6RTC If the standard plug is apt to overheat, replace with the

plug.

z Tighten the spark plug to the specified torque.

Spark plug

Tightening torque:15-18N.m

NOTE:

z To check the spark plug, first make sure that the fuel used is unleaded gasoline,

and if plug is either sooty with carbon or burnt white, replace it.

z Confirm the thread size and reach when replacing the plug.

FUEL LINE

Inspect at initially 500 km and every service,

replace every 4 years.

12

AIR CLEANER

Clean every 3000KM（2000 miles）

If the air cleaner is clogged with dust, intake resistance will, be increased with a resultant

decrease in power output and an increase in fuel consumption. Check and clean the element

in the following manner.

 Remove screw 1 and screw 2，take down air cleaner

 Unscrew tapping screw 3，remove air cleaner cap 4

 Fill a washing pan of a proper size with Non-flammable

cleaning solvent. Immerse the air Cleaner in the cleaning

solvent and wash them clean.

 Squeeze the cleaning solvent out of the washed element

By pressing it between the palms of both hands: do not

twist

or wring the air cleaner filter core element or it will

develop tears.，

 Immerse cleaned filter core of air cleaner in CCI or CCI

SUPER oil, and squeeze the oil out of the core，which

may be slightly wet with oil.

 Install air cleaner filter core in the reverse order of

removal.

CAUTION：

 Before and during the cleaning operation, inspect the core

for tears. A tore core must be replaced

 Be sure to position the filter core, so that no incoming air will

bypass it. Remember, rapid wear of piston rings and

cylinder bore is ofter caused by defective or poorly fitted

filter core.

 Finally adjust the throttle cable play.

OIL PUMP

Inspect at initially 500km and every

year.

The engine oil is fed by the oil pump to the engine. The amount of oil fed to it is

regulated by engine speed and oil pump control lever which is controlled by amount

of throttle opening.

Check the oil pump in the following manner to confirm correct operation for throttle

valve full opening position.

 Turn the throttle grip full open.

 Check whether the red mark on the oil pump control lever

Is aligned with the index mark when the throttle valve is positioned as above.

 If the marks are not aligned, loosen lock nuts and turn the adjuster in or out to

align the marks.

 After align the marks, tighten the locknuts.

Caution：

Oil pump calbe adjustment must be done after

throttle cable adjustment.

GEAR OIL

Change as shown in the

service schedule.

Inspect gear oil periodically as follows:

 Remove the cover and hose

 Remove the kicking starter lever

 Remove clutch cover

 Remove oil level bolt and inspect oil level,

if oil level is below oil hole, add oil until oil

flows from the level hole.

 Tighten oil level bolt to the specified torque.

Tightening toque：9-15N.m

（0.9-1.5 kg-m ，6.5-11.0 lb-ft）

BRAKES

Inspect at initially 500 km and every service,

replace brake fluid every 2 years, replace

brake hose every 4 years.

Front brake fluid level

 Keep the scooter upright and place the

handlebar staight.

 Check brake fluid level by observing the

lower limit line on the brake fluid reservoir.

 When the level is below the lower limit line,

replenish with brake fluid that meets the

following specification.

Specification and classification：DOT4

WARNING：

The brake system of the scooter is filled with a glycol-based brake the lowest line

Fluid. Do not use or mix different types of fluid such as silicone-based and

petroleum-based. Do not use any brake fluid taken from old, used or unsealed

containers. Never reuse the brake fluid left over from the last servicing and stored for

long periods.

15

WARNING：

Brake fluid, if it leaks, will interfere with safe running and immediately

discolor painted surfaces.

Check the brake hoses for cracks and hose joints for leakage before

riding.

Brake pads

Wearing condition of brake pads can be checked by

observing the limit line  marked on the pad. When the

wear exceeds the limit mark, replace the pads with

new ones.

Bleeding air from the brake fluid circuit

Air trapped in the fluid circuit acts like a cushion to

absorb a large proportion of the pressure developed by

the master cylinder and thus interferes with the full

braking performance of the brake caliper. The

presence of air is indicated by “sponginess” of the

brake lever and also by lack of braking force.

Considering the danger to which such trapped air

exposes the machine and rider, it is essential that, after

remounting the brake and restoring the brake system

to the normal condition, the brake fluid circuit be

purged of air in the following manner:

 Fill up the master cyliner reservoir to the upper end

of the inspection window. Replace the reservoir cap

to prevent entry of dirt.

 Attach a pipe to the caliper bleeder valve, and insert

the free end of the pipe into a receptacle.

Bleed air from the bleeder valve.

Squeeze and release the brake level several times

in rapid succession. And squeeze the lever fully

without releasing it. loosen the bleeder valve by

turning it a quarter of a turn so that the brake fluid

runs into the receptacles: the will remove the

tension of the brake lever causing it to touch the

handlebar grip. Then, close the valve, pump and

squeeze the lever, and open the valve. Repeat the

process until the fluid flowing into the receptacle no

longer contains air bubbles.

16

NOTE：when bleeding the braking system, replenish the brake fluid reservoir if

necessary. Make sure that there is always some fluid visible in the reservoir.

 Close the bleeder vavle, disconnect the pipe. Fill the reservoir with brake fluid to

the upper end of the inspection window.

BLEEDER VALVE

TIGHTENING TORQUE: 6-9N.m(0.6-0.9kg-m,4.5-6.5lb-ft)

CAUTION：

Handle brake fluid with care: the fluid

reacts chemically with paint, plastics,

rubber materials, etc.

Rear brake

Turn adjusting nut so that the the play of the

brake lever is 15-25MM as shown in the

illustration.

Brake shoe wear：

The vehicle is equipped with the brake

lining limit Indicator on the rear brake.

Inspect brake lining limit as follows：

1. First check if the brake system is properly

adjusted.

2. when operating the brake, check to see

that the tip of indicator is within the range.

3. if the tip of indicator is beyond the range,

the brake shoe assembly should be

raplaced with anew set of shoe.

17

Tire

Inspect at initially 1000KM （600 miles ，2

months） and every 6000KM（4000 miles，12

months）thereafter

Tire pressure：

If the pressure is too high, the scooter will tend to rede

stiffly and have poor traction. Conversely, if tire

pressure is too low, stability will be adversely affected.

Thereafter, maintain the correct tire pressure for good

roadability and to prolong tire life.

CAUTION：

The standard air pressure of tires is 175/196Kpa, the use

of other than standard may cause handling instability. It is

highly recommended to use a GENERIC genuine tire.

Tire tread condition：

Operating the scooter with the excessively worn tires

will decrease riding stability and consequently invite

dangerous situation. It is highly recommended to

replace the tire when the remaining depth of tire tread

reaches the following specification.

Front and rear：1.6MM（0.064IN）

Tire depth gauge

Steering

inspect at initially 500km and every

service.

Steering should be adjusted properly for smooth turning

of handlebars and safe running. Too stiff steering

prevents smooth turning of handlebars and too loose

steering will cause poor stability.

Check that there is no play in the front fork assembly by

supporting the machine so that the front wheel is off the

ground, with wheel staight ahead, grasp lower shock

absorber near the axle and pull forward. If play is found,

perform steering bearing adjustment.

18

Front shock absorber

Adjust at initially 500km and each

service.

Inspect the front shock absorber for oil leakage or other damage, and replace the

defective parts, if necessary.

Rear shock absorber

Adjust at initially 500km and each

service.

Inspect front shock absorber for oil leakage and other damage, and replace the

defective parts if necessary.
